CHURN.

Application filed May 29, 1922. Serial No. 564,507.

T 0 all whom it may concern Be it known that we,'Dnn Aynns and HAL DEE Fossnrr, citizens of the United States, and residents of Mount Vernon, inthe county' of Lawrence, in the State of Missouri, have invented certainnew and useful Improvements in Churns, of which the following is aspecification.

This invention relates to agitators or churns especially adapted for useas a butter churn, a cream whipper, a pastry mixer and the like.

Briefly stated an important object of this invention is to provide novelmeans whereby the agitators may be applied to receptacles of variousheights.

Also the invention forming the subject matter of this application aimsto provide an agitator having simple means whereby the same may beapplied to receptacles of various widths.

Also the invention aims to provide an agitator which is smooth inoperation, of highly simplified construction and cheap to manufacture.

Other objects and advantages of the in vention will be apparentduring'the course of the following description.

In the accompanying drawing, forming a part of this application and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a perspective of the improved agitator for the churn.

Figure 2 is a vertical sectional view through the improved agitator.

Figure 3 is a detail horizontal sectional view illustrating a guideembodied in the invention.

In the drawing, wherein for the purpose of illustration is shown apreferred embodiment of the invention, the numeral 5 generallydesignates a receptacle of any desired shape or size and which asillustrated in Figure 2 isprovided with a closure 6 to which theconstruction forming the subject matter of this application is applied.

The churn comprises a triangular frame having a pair of inclinedstandards 8, said standards having their lower ends formed with basemembers or feet 10 secured to the lid or closure by means of fasteningdevices 12. It will be observed that the height of the frame may bevaried to some extent by moving the attaching portions 10 away from ortoward each other. By reason of this construction the frame may beapplied to receptacles of various sizes.

The upper portions of the standards 8 are secured to opposite sides of abearing member or head block 14:, the said head being formed from alength of sheet metal or. other suitable material bent between its endsto provide the opening for the reception of.

the crankand the ends of the piece of metal are arranged flatly incontact with each other and between the upper portions of the standards8. Suitable fastening devices,

such as bolts 15 may be'extended through fined between the standards andthe saidguide strip 17 may be provided with openings for the receptionof the fastening devices 15 whereby the guide strip issecurely held inposition. The end portions of the guide strip 17 are arranged inU-shaped formation and cooperate with one side of thebearing member 14indefining an opening for the reception of dasher members 18.

The dasher members 18 are square in cross section and have their lowerends formed with a itating devices 20 of any desired type. he agitatorrods 18 are slidable through'the closure 6 and are guided thereby and bythe U-shaped guide members 17 so that the dasher rods cannot get out ofposition. A shaft 23 is rotatably extended through the bearing member14: and is provided with oppositely directed cranks connected to bearingmembers 25.

In carrying out the invention the bearing members 25 of which there aretwo are formed from single lengths of metal bent intermediate their endsto provide openings for thereception of the cranks of the shaft 23 andthe end portions of the several lengths of metal are arranged flatly incontact with each other and are formed with openings for the receptionof the attaching portions 26 of pitm'an rods 27. It will be observedthat the return bends which define the attaching hooks 26 dispose theattaching hooks flatly in contact with the adjacent sides of the bearingmembers and thereby hold the end portions of the strips, of metalagainst spreading. The connection thus provided between the crank shaftand the pitman rods 27' absolutely prevents binding and provides asmooth connection between the parts.

Figure 1 illustrates that the lower portions of the pitman rods areextended laterally to provide dasher receivingmembers 30 which arereceived within transverse grooves 31 in the dasher rods 18. Suitableplates 33 are applied to the rods 18 and extend over the attachingportions 30 for connecting the same to the dasher rods. It will beobserved that there are a plurality of transverse grooves 81 in eachdasher rod so that the connection between each rod 27 and the associateddasher rod may be varied as the occasion requires. That is to say theeffective length oi the dasher rod may be Varied for use in connectionwith shallow and deep receptacles.

Summarizing this invention, it will be observed that the bearing memberlet which is disposed between the upper portions or the standards 8 notonly serve as support ing means for the crank shaft but also at one sideof the guides for the dasher rods 18. The bearing member i l also servesas a spacin element for the upper ends of the standarc s 8.

In operation the handle 38 of the crank shaft is rotated for moving thepitmen mem bers 27 vertically. The movement thus imparted to the pitmanrods 27 causes the dasher rods to move vertically for rapidly agitatingthe contents of the receptacle.

The particular connection between the pitman rods 27 and the crank shaftprovides an extremely smooth connection between the several parts sothat no binding will occur and consequently the churn may be operatedwith a minimum of efliort on the part of the operator.

Having thus described the invention, what we claim is A churn comprisinga receptacle, a closure carried thereby, a frame mounted on said closureand inclusive of a pair of converging standards, a bearing member formedfrom a single length of metal bent intermediate its ends to provide atransverse bearing opening and a pair of attachin plates, said attachingplates being arranged flatly in contact with each other and beingconfined between the upper portions of said standards, a crank shaftextending through said transverse bearing opening and having oppositelyarranged cranks, a guide strip having its intermediate portion conlinedbetween the upper portions of said standards and having its end portionsarranged in U-shaped formation and co-opcrating with said bearing memberin defining a pair of vertical guide openings, dasher rods movablethrough said vertical guide openings and through said closure and guidedthereby, pitman rods connected to said dasher rods and said crank shaft,and fastening devices extending through the up per portions of saidconverging standards, the intermediate portions of said guide strip andthe attaching plates of said first named bearing member.
